Sure, let's start to create our named tuple 'Dog'.
Firstly, we have to import the module `namedtuple` from the library `collections`.
What exactly is a named tuple? A named tuple is just like an ordinary tuple but with names and it can be used as a class.
For this question, we will create a named tuple 'Dog' with attributes 'name', 'breed', and 'color'. This is done by calling namedtuple with the desired type name and a list or string containing the names of the elements/fields as parameters.
Next step is to return this new tuple type 'Dog'.
This new type can be used to create new tuple objects with the specified attributes 'name', 'breed', 'color'.
Meanwhile, the tuple type 'Dog' is defined within the function `solution`, which means this 'Dog' type is only available within this function.
Running this function `solution` will return the new tuple type 'Dog' that we've created. In Python's internal representation, it shows up as ``. This means that our function successfully created a new namedtuple type called 'Dog'.
This is a very common way of grouping data in Python, making the code easy to manage and further modify if necessary. Namedtuple provides a quick way to create a new object/class type with some attribute fields, just like what we did for 'Dog' with attributes 'name', 'breed', 'color'.
